Abstract:
In order to get a relatively objective assessment for the storm cell identification and tracking (SCIT) and the mesocyclone detection algorithm (MDA) products’ application in China, and then to provide reference of the products for future use, the performance evaluation of two kinds of products on the current business has been done based on the 2007—2008 disaster weather case archives offered by CMA Meteorological Observation Centre. The results of the evaluation are compared with the United States’ and show that the SCIT products can meet the basic needs of nowcasting, but the leak detection and error tracking exist, and when the lead time exceeds 30 min, the location prediction error can be big. The performance evaluation of MDA products can be considered similar to the United States’, and basically can automatically identify the storm vortex, but there are still some missings, and the false alarm rate is high.
